当我尝试调用远程接口时，这段代码有一些问题，即部署在其他服务器（Weblogic）中。
这是我的客户：
package service;
import java.util.*;
import javax.ejb.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.ws.rs.*;
@Path("/")
@Stateless
public class GestionPersonnel {
Context ctx;
@GET
@Produces("application/json")
@Path("requete")
public void test() throws NamingException{
Hashtable<Object, Object> env = new Hashtable<Object, Object>();
// WebLogic Server 10.x connection details
env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7001");
env.put(Context.SECURITY_PRINCIPAL, "dream");
env.put(Context.SECURITY_CREDENTIALS, "dream123");
Context ic = new InitialContext(env);
MetamodelService metamodelService = (MetamodelService) ic.lookup("MetamodelContentService#com.evision.metamodel.services.MetamodelService");
Euser user = metamodelService.findEuserByUserName("aaaaa@tata.ca");
System.out.println(user.getFirstName());
};
@GET
@Produces("application/json")
@Path("requete2")
public String test2() {
return "hello";
}
}
当我试图在我的客户端中调用此函数时（MetamodelService metamodelService = (MetamodelService) ic.lookup("MetamodelContentService#com.metamodel.services.MetamodelService");）我有这个问题：
